2 Claims The object of my invention is a new process for making and applying an arch support for womens shoes, and to provide a process by which the necessary arch support is applied at less expense than has been possible with previous methods.

The principal steps in carrying out the process are illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the leather from which the sole of the shoe is prepared, in the single-sole process of shoe construction;

Fig. 2 is a section on line 2--2 of Fig. 1;

Fig. 3 is a section on line 33 of Fig. 1;

Fig. 4. is a perspective view of the outer sole and inner sole, which is formed by splitting the leather after it has been cut into proper form for the shoe from the rough blank, in the singlesole process of shoe construction, as shown in Fig. 1;

Fig. 5 is a perspective view of the stiffening strip 8 by itself;

Fig. 6 is a perspective View of the inner sole (single-sole process of shoe constructiionj) in inverted position with the stifiening strip 8 affixed to it; I

Fig. '7 is a bottom plan View of my arch support member H for the left shoe;

Fig. 8 is a section on line 8-8 of Fig. '7;

Fig. 9 is a section on line 9-9 of Fig. 7;

Fig. 10 is a perspective view of the inner sole (single-sole process of shoe .construction) for the right shoe with both members 8 and II secured to it;

Fig. 11 is a section on line ll--l I of Fig. 10;

Fig. 12 is a perspective View of the inner sole (single-sole process of shoe construction) with members 8 and H afiixed thereto, and with the arch extension [4 of member H molded into the upwardly curved shape required to fit the shoe;

Fig. 13 is a section on line l3-l3 of Fig. 12; and

Fig. 14 is a section on line l4|4 of Fig. 12.

Like characters of reference designate like parts in each of the several views.

Leather blanks B, as shown in Fig. 1, are bought in rough outline, and from these blanks the leather sole is cut following the outline of the foot as indicated by the dot and dash line, 0. In the single-sole process of shoe construction the sole is then split longitudinally to form the outer sole l and inner sole 2, as shown in Fig.

4. In doing this there is no way to have the arch support as part of the inner sole, unless it (01. 12-146) y i i x is attached to it either by having it sewed "on or stitched on.

In Figs. 2 and 3 of the drawings, numeral 3 is the, line of splitting between the outer sole I and the inner sole 2, and the numeral 4 designates the portion of the outer sole which is not split (single-sole process of shoe construction). The heel of the inner sole is designated as 6, and the heel of the outer sole is designated as l. I provide the usual heel stiffening strip 8, which is beveled at 9 and is afiixed to the underside of the inner sole, either by suitable staples H3, or by cementing it to that member.

I provide an arch support strip II, with an arch extension M. This strip is of suitable material such as reinforced leather or fibre. It is secured on the upper or inner side of the inner sole by suitable means such as staples l3, or by cementing or sewing, or stitching it to the heel portion '6 of the inner sole 2, as shown in Fig. 10.

As the next step in the process, the arch extension portion I4 is tempered or mulled and shaped into a curved shape to conform with the shape of the arch of the foot. The inner sole is then ready to go into the usual and conventional process of shoe construction.

By following this method I eliminate any artificial means for making an arch support such as by inserting additional strips of leather. My method eliminates seams, ridges and various uncomfortable obstructions which occur in the shoes built by prior methods. When the uppers have been secured to the inner sole by suitable means as by cementing or sewing, as a final step the sock lining is inserted over the inner sole and its arch support H, the sock lining members not being shown in the drawings and not being a part of my invention.

My method eliminates heavy expenditures for dies, as no die is necessary since the conventional shapes of inner and outer soles can be purchased in the required form. Likewise, the stiffening strip 8 is of conventional shape and can be purchased in the market.

My method makes possible an arch shoe in the single-sole method of constructionsomething which was impossible before under thatprocess other than by using a small piece stitched on as heretofore explained.

My method as applied to the two sole method of construction is as follows:

A piece of leather is purchased in the open market for an outer sole and a similar shaped piece of leather of a somewhat lighter Weight is purchased for an inner sole. These are the usual PATENT OFFICEA conventional forms. Both of these soles, the inner and outer, are either cut out by die or rounded out into suitable shapes. From there on the process is the same in both the two sole and. the single-sole construction. The only difference between the two types of construction is, in the single-sole one piece of leather is used and split to form both the outer and inner sole. In the two sole method of construction two soles are purchased-one for an inner sole and one for an outer sole. In carrying out this process I do not necessarily bevel the ends of the member II, as at l2, and this process thus eliminates the cost of beveling or skiving or bufiing down.

I also use a metal reinforcing arch strip, not shown in the drawings as this is a conventional element and used by all manufacturers and is not a part of this invention.

My new process makes it possible to have light and dainty womens arch support shoes.

What I claim is:

1. The process of making and. applying arch supports for shoes, consisting in affixing a stifiening strip to the underside of the inner sole, afiixing an arch support strip extending only over the heel and shank of the sole to the upper side of the inner sole, said arch support strip having a laterally projecting member integral therewith to support the arch, and molding and tempering said laterally projecting member to conform with the curve of the arch of the foot.

2. The process of making and applying arch supports for shoes, consisting in cementing a stifiening strip to the underside of the inner sole, cementing an arch support strip extending only over the heel and shank of the sole to the upper side of the inner sole, said arch support strip having a laterally projecting member integral therewith to support the arch, and molding and tempering said laterally projecting member to conform with the curve of the arch of the foot.
